Description

Technical Field

[0001] The utility model belongs to the field of electrical equipment, and particularly relates to an electrical wiring device. Background Art

[0002] The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most crucial factor for electricity to operate and be transmitted normally in a power plant is electrical equipment. Electrical operations must be carried out by personnel who have received professional training, passed the examination, and hold a work operation certificate for staff. Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in the power system. During the installation process of electrical equipment, it is necessary to connect the wires into the electrical junction box for connection control, which can not only ensure the connection stability but also improve the control accuracy and safety. The electrical junction box is one of the indispensable components in the electrical system.

[0003] For the existing electrical junction box, the box body and the box cover are threadedly connected. The bolt passes through the threaded holes inside the box cover and the junction box body, and then a tool is used to fix the bolt. Tightening the bolt realizes the fixed connection between the box body and the box cover. When it is necessary to disassemble, install, and fix the wires inside the box, a disassembly and installation tool is used to open the box cover to adjust and fix the wires inside. This is not only time-consuming and laborious but also has low efficiency. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides an electrical wiring device. By means of a flipping cover-closing mechanism, the movable box cover is opened or closed, realizing the rapid separation or combination of the junction box body and the movable box cover, and the operation is convenient and fast.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An electrical wiring device, which includes a junction box body and a movable box cover connected to the junction box body and covering and closing the opening of the junction box body. A wire connector for connecting wires is fixed inside the junction box body. A cover-closing mechanism for restricting the opening and closing of the movable box cover is connected to the junction box body. The cover-closing mechanism includes rotating supports arranged on both sides of the junction box body, movable sliding rods sliding along the rotating supports, and a connecting cross bar connected between the movable sliding rods. A plurality of inlet sleeves for introducing wires into the inside of the junction box body are provided on the side wall of the junction box body.

[0007] Further, the rotating support includes a movable sleeve rotatably connected to the junction box body and a movable bottom plate sliding along the inner wall of the movable sleeve. An opening for the movable sliding rod to extend out is opened on the top plate of the movable sleeve, and a blind hole is opened on the bottom plate of the movable sleeve.

[0008] Further, a support pillar is provided on the side wall of the junction box body corresponding to the blind hole. One end of the support pillar extends into the blind hole, enabling the rotary support to rotate with the support pillar as the rotation axis.

[0009] Further, the bottom end of the movable slide rod is connected to the movable bottom plate. The top end of the movable slide rod extends out of the opening of the movable sleeve and is connected to the connecting cross bar. A compression spring is sleeved on the movable slide rod between the top opening of the movable sleeve and the movable bottom plate.

[0010] Further, a plurality of spaced-apart inserts protruding towards the junction box body are fixed on the connecting cross bar. For example, there can be two inserts, which are respectively arranged at positions of the connecting cross bar close to the movable slide rod. The length of the connecting cross bar is greater than the distance between the two movable slide rods, such that both ends of the connecting cross bar protrude beyond the movable slide rods, facilitating the staff to hold the connecting cross bar.

[0011] Further, a transverse groove for accommodating the connecting cross bar is formed in the movable box cover. Fixing jacks corresponding to the positions of the inserts are formed in the transverse groove. The fixing jacks are adapted to the inserts. When the movable box cover is closed, the transverse groove is directly above the connection line of the two support pillars, and the depth of the transverse groove is consistent with the height of the connecting cross bar. When the inserts are inserted into the fixing jacks, the connecting cross bar falls into the interior of the transverse groove, keeping the top of the movable box cover flat. When it is necessary to open the movable box cover, the staff holds both ends of the connecting cross bar and pulls the connecting cross bar upward against the resistance of the compression spring to extract the inserts from the interior of the fixing jacks. Then, the connecting cross bar and the movable sleeve are rotated clockwise to rotate the connecting cross bar away from the movable box cover. When the connecting cross bar rotates to the outside of the junction box body, the movable box cover is released from the restraint of the connecting cross bar, and the staff opens the movable box cover. When it is necessary to close the movable box cover, the movable box cover is buckled onto the opening of the junction box body. The connecting cross bar and the movable sleeve are rotated counterclockwise to position the connecting cross bar directly above the transverse groove of the movable box cover, aligning the inserts with the fixing jacks. The connecting cross bar is released, and the connecting cross bar drives the inserts to quickly descend and insert into the interior of the fixing jacks under the rebounding action of the movable bottom plate and the compression spring, restricting the opening of the movable box cover.

[0012] Further, the inlet sleeves are arranged on two opposite side walls of the junction box body and protrude away from the junction box body. For example, the inlet sleeves are integrally connected to the junction box body. An annular threaded seat is provided on the outer part of the inlet sleeve, and the threaded seat is fixed on the side wall of the junction box body. Internal threads are provided on the inner wall of the threaded seat. Conductors pass through the inlet sleeves and extend into the interior of the junction box body to be connected to the connectors.

[0013] Further, a protective sleeve is threadedly connected between the threaded seat and the incoming line sleeve. The protective sleeve includes a connecting shell connected to the threaded seat and a conical end fixed to one end of the connecting shell. The outer wall of the connecting shell is provided with an external thread matching the internal thread of the threaded seat. The protective sleeve is composed of two half sleeves, and the half sleeve is formed by radially bisecting a complete protective sleeve. The inner diameter of the connecting shell is preferably the same as the outer diameter of the incoming line sleeve, and the inner diameter of the conical end is preferably the same as the outer diameter of the wire. When using the protective sleeve, the two half sleeves are placed on both sides of the wire, and the two half sleeves are closed towards the wire to enclose the wire inside the protective sleeve. The connecting shell is screwed into the threaded seat for fixation to protect the incoming line sleeve and the wire threading part and fix the wire. When it needs to be removed, the connecting shell is rotated in the reverse direction to withdraw one end of the protective sleeve from the inside of the threaded seat. After withdrawing from the threaded seat, the two half sleeves are separated, and the protective sleeve is removed from the wire.

[0014] Further, heat dissipation grooves are provided on the side walls of the junction box body where no incoming line sleeve is provided. There are multiple heat dissipation grooves arranged at intervals, and the heat dissipation grooves are distributed horizontally or vertically. The heat dissipation grooves promote the air circulation inside the junction box body and ensure the heat dissipation effect inside the junction box body.

[0015] Further, a filter dust-proof net is covered outside the heat dissipation grooves. The filter dust-proof net is preferably detachably connected to the junction box body, for example, by using bolt connection. The filter dust-proof net filters the air entering the inside of the junction box body to prevent dust and impurities from entering the inside of the junction box body through the heat dissipation grooves. By removing the bolts on the filter dust-proof net, the filter dust-proof net is removed from the junction box body for easy cleaning of the filter dust-proof net.

[0016] Further, a plurality of information card sockets are fixed on the outer surface of the movable box cover. The information card sockets are transparent. By providing the information card sockets, it is convenient to install the information cards displaying the wiring wire information, and the wiring information inside the junction box body can be accurately and quickly understood.

[0017] Further, the information card sockets are arranged corresponding to the incoming line sleeves so as to accurately display the internal wiring information of the junction box body corresponding to each incoming line sleeve.

[0018] Further, the movable box cover is hinged to the junction box body.

[0019] The beneficial effects of the present utility model:

[0020] An electrical wiring device of the present utility model forms an occlusion to the wiring box body by closing the movable box cover on the top of the wiring box body. The insertion block on the connecting cross bar is inserted into the interior of the fixed insertion hole under the push of the compression spring to limit the flipping and opening of the movable box cover. By pulling the movable slide bar upward to extract the insertion block from the interior of the fixed insertion hole, and then making the insertion block away from the movable box cover through the flipping closing cover mechanism, the rapid opening of the wiring box body and the movable box cover can be realized, simplifying the opening process of the movable box cover, with simple disassembly and assembly, and improving the operation convenience.

[0021] The wire inserted into the interior of the inlet sleeve is fixed by the provided protective sleeve, and different-sized wires can be fixed by replacing the tapered ends of different sizes, increasing the types of connected wires and improving the protection effect on the wire joint. By wrapping the wire with the tapered end, dust and moisture are prevented from invading, improving the service life and safety of the wire joint. By rotating the protective sleeve to take out the protective sleeve from the interior of the threaded seat and separating the two connecting shells to remove the protective sleeve from the wire, the disassembly is convenient and the maintenance efficiency is improved.

[0022] The interior of the wiring box body is ventilated and cooled through the heat dissipation slots, and the air passing through the heat dissipation slots is filtered by the provided filter dust screen to prevent impurities and dust from entering the interior of the wiring box body. And it is convenient to disassemble and clean the filter dust screen by removing the bolts on the filter dust screen. Description of the Drawings
